[Elecraft] Inverted-L (was OT: Vertical antenna)

[ARDUJENSKI at aol.com]

Going from loop to vertical involves two very different lob patterns. It  
was never mentioned if the antenna performance was to favor local or DX. Here 
is  one which it does not matter as it adapts for both.
 
A nice compromise antenna which takes into account:
---high and low angle lobe patterns
---good match (resonant on 80m)
---small footprint
 
======DESCRIPTION===============================


 
 INVERTED-L: 33 ft vertical, 33 ft top wire, feed at base against 12 16ft  
 radials. I use Radio Shack low loss 300 ohm tv wire for feed
  
 According to calculations EZNEC had a 40ft top wire. In the field I 
trimmed it until we got an  
 acceptable match on several bands
  
 For supports I have used the DK9SQ mast as the main and used the Black 
Widow  20ft 
 for the end support with great success
 ----------------------------------------------------
 I use RCA connectors for many of my antennas. I install male RCAs on wires 
 
 and interconnect with using DOUBLE FEMALES. For 300 ohm TV wire I will 
solder  
 short piece of speaker wire to each of the conductors and then securely 
tape 
 the  soldered area to the ribbon insulator body . To the end of each 
speaker 
 wire I  afix a MALE RCA. Generally I will make one speaker wire on each 
end a 
 little  shorter (3/4 inch) so I can tell easily identify which wire is 
which. 
 The RCAs  work great and it they break off in the field I carry wire nuts 
for  
 emergencies
 ----------------------------------------------------
 I have EZNEC pattern (PDF) for several bands and also a sketch for the  
300 
 ohm connection if you want more details
 ----------------------------------------------------
 Note at the QTH I have used this for 80 and 160m with good success  
including 
 contacts with Japan on 160m. I am sure the key is the other fellows  has 
HUGE 
 arrays but it worked. 
  
 Hope this helps
